When SunEdison went through difficult layoffs in October 2015, hundreds were let go -- but the folks in the C-suite were mostly left unscathed. As GTM's Stephen Lacey reported, "The cuts have reached all the way to the VP level, but not the executive level. Sources within the company expressed worry and surprise that the cuts didn't impact the architects of the Vivint acquisition."

The other shoe has started to drop.

According to Julien Dumoulin-Smith at UBS, Steve Tesoriere, "an activist investor [who] played a key role in developing SunEdison’s YieldCo strategy," has resigned from the solar and wind developer's board. Tesoriere's Altai Capital Management owns approximately 2.3 percent of SunEdison, according to a proxy filing. UBS notes, "Tesoriere was also one of four to resign as a board member of SunEdison YieldCo TerraForm Power in November 2015."

According to UBS, Paul Gaynor (former First Wind CEO) has also departed, although this was not disclosed in the 8K filing. "Given Paul's former role as CEO of First Wind, we continue to perceive growing risk to execution on guided targets, particularly on wind backlog," reported UBS.
